You can do this today, as long as you know what chips you plan to remove ahead of time.

On the Rounds tab, edit the break where you intend to chip up. Then press the Tokens button. Add a token named "breaktext", and change the value to whatever you want, like "Pause, 500's color up". During the break, the text displayed which is usually "Break" will be the value you put in for the "breaktext" token.
